.. saslman:: sasl_setprop(3)
.. _sasl-reference-manpages-library-sasl_setprop:
======================================
**sasl_setprop** - Set a SASL property
======================================
Synopsis
========
.. code-block:: C
#include <sasl/sasl.h>
int sasl_setprop(sasl_conn_t *conn,
int propnum,
const void * pvalue)
Description
===========
.. c:function:: int sasl_setprop(sasl_conn_t *conn,
int propnum,
const void * pvalue)
**sasl_setprop** sets the value of a SASL property. For example an
application should tell the SASL library about any external negotiated
security layer (i.e. TLS).
:param conn: is the SASL connection context
:param propnum: is the identifier for the property requested
:param pvalue: contains a pointer to the data. It is the applications
job to make sure this type is correct. This is an easy way to crash a
program.
* SASL_AUTH_EXTERNAL ‐ external authentication ID (const char \*)
* SASL_SSF_EXTERNAL ‐ external SSF active ‐‐ (sasl_ssf_t)
* SASL_DEFUSERREALM ‐ user realm (const char \*)
* SASL_SEC_PROPS ‐ `sasl_security_properties_t` (may be freed after call)
* SASL_IPLOCALPORT ‐ string describing the local ip and port in the form
"a.b.c.d;p", or "e:f:g:h:i:j:k:l;port"
* SASL_IPREMOTEPORT ‐ string describing the remote ip and port in the form
"a.b.c.d;p", or "e:f:g:h:i:j:k:l;port"
Return Value
============
SASL callback functions should return SASL return codes.
See sasl.h for a complete list. :c:macro:`SASL_OK` indicates success.
Other return codes indicate errors and should be handled.
